Sons of Anarchy Star Turned Murderer May Have Fathered Love Child Before Death (UPDATE)

Update (10/7/2013): According to court documents obtained by TMZ, Johnny was officially named the father of Diane's baby girl prior to his death in 2012. On the baby's birth certificate, her parents are listed as Diane Gaeta (now known as Diane Marshall-Green) and Johnny Lewis, which was signed off on by Diane at the time. Now that there is more definitive evidence of the child's paternity, Johnny's estate will likely go toward providing for his child, rather than to the late actor's parents.

Original story: Late Sons of Anarchy star Johnny Lewis may have left one final mystery behind for his friends and family to solve.

The actor, who starred as Kip “Half-Sack” Epps, on the FX hit, was accused of murdering his landlady, Catherine Davis, and playing operation with her cat before falling off the roof of his Los Feliz, California home to his death, in September 2012.

However, it appears that, prior to totally losing it, Johnny may have fathered a child with one of his Sons of Anarchy co-stars.

In an effort to close out the actor’s estate, Johnny’s family asked an L.A. Superior Court to divide the actor’s assets among applicable parties, which, according to court documents, include actress Diane Marshall-Green and her child.

According to TMZ, Johnny’s attorney admits that the star was convinced he was the father of Diane’s 3-year-old daughter and even petitioned for visitation of the toddler before his death.

However, Johnny’s dad doesn’t believe the girl is his grandkid and is trying to have all of Johnny’s money — a grand total of $41,000 — given to him and Johnny’s mom instead.

Diane, wife of Prometheus star Logan Marshall-Green, has not commented on her child’s paternity.
